TriQuint`s GaN devices target defence systems

The firm's latest gallium nitride based optical and base station modules enhance RF amplifiers

TriQuint Semiconductor is releasing a variety of new GaN transistors that offer superior gain, thermal management and efficiency for commercial and defence RF amplifier designs.

“TriQuint continues to address our customers’ next generation requirements by delivering innovative high performance RF solutions. Products span from new industry-leading optical modulator drivers, to a new family of Small Cell amplifiers, to Spatium PAs that replace TWTAs, and our ever-growing portfolio of GaN based products and processes. TriQuint innovation is shaping the future for system performance and cost reductions,” remarks James L. Klein, Vice President and General Manager for Infrastructure and Defense Products.

New GaN Solutions

TriQuint is announcing two new high-power GaN packaged transistors including the 200 W (Watt) T1G4020036-FS/FL and the 285 W T1G2028536-FS/FL.

Both devices offer excellent gain, which enables smaller RF amplifiers and reduced part-counts in many applications; both devices are widely exportable.

The T1G2028536-FS/FL covers DC-2 GHz while the T1G4020036-FS/FL covers DC-3.3 GHz; both devices are ideal for commercial and defence applications including professional communications, commercial and defence radars, avionics and RF test systems.

TriQuint’s new GaN transistors are joined by new GaN amplifiers and low-noise amplifiers that also deliver high efficiency and improved performance compared to competing products for wide-ranging commercial and defence applications.

New GaN products include wideband LNAs covering 2 - 6 and 6 - 12 GHz with excellent gain. New amplifiers include a family of solutions that focus on the needs of S-band radar and other key frequencies with excellent gain and efficiency.

Small-Cell Innovation

TriQuint is introducing the first in a new family of ‘small cell’ integrated power amplifiers that also serve active antenna base stations. The new TGA2450-SM amplifier dramatically reduces board space while delivering high efficiency as a key component in 3G/4G mobile networks including LTE. 


The TGA2450-SM is sampling and now available; it meets Band 1 requirements while reducing PCB areas 50%. TriQuint has integrated amplifier solutions in development for additional global cellular bands. Contact TriQuint for details and sample information.

SMT Optical Solutions

TriQuint also recently added four new SMT optical network modulator drivers to its portfolio. These products expand the company’s line-up with devices that include miniaturised and integrated modules. TriQuint high performance optical components reduce overall system costs, simplify RF design and shrink board space for today’s 100 Gb/s optical fibre networks and future 200/400G systems.

Spatium Replaces TWTAs

TriQuint acquired CAP Wireless and its Spatium RF power combining technology that replaces travelling wave tube amplifiers (TWTAs) in communications and defence systems.

This technology expands the firm's expertise in high power RF solid-state amplifier systems. Spatium technology adds to the exceptional efficiency, bandwidth and ruggedness of TriQuint’s product portfolio. 

In high power RF applications, Spatium delivers superior broadband RF power efficiency through the use of patented coaxial spatial combining techniques. Spatium provides other performance advantages including solid-state reliability, smaller form factors, higher power densities and reduced weight compared to either TWTA-based systems or conventional planar power combining products. Contact TriQuint for Spatium product details.

TriQuint will be showcasing its power devices at the Nuremburg Convention Centre during European Microwave Week (EuMW) at stand 130/141 , taking place from October 8th to 10th.
